An aluminum carbenoid is the efficient cyclopropanation reagent for the transformation of 2-alkenyl amines into cyclopropyl amines. The addition of iodine facilitates the cyclopropanation of poorly reactive 2-alkenyl amines.

to improve growth inhibitory activity against MRSA. Among the MenA inhibitors, bicyclic substituted amine 3 showed MIC of 3 µg/mL, and alkenyl substituted amine 11 showed MIC of 8 µg/mL against USA300. Regrowth of MRSA was observed on addition of MK when exposed to 8 µg/mL of inhibitor 11, supporting inhibition of MK biosynthesis. However, inhibitor 11 did not show efficacy in treating USA300 infected
